o encode 24 greek distinct lowercase letters, you should be able to write in binary language 24 different combinations.

With 1 bit you have only 2 possible combinations. Not enough.

With 2 bit you have only 4 possible combinations. Not enough.

With 3 and 4 bit you have only 8 and 16 possible combinations. Not enough.

With 5 bit you have 32 possible combinations. This is enough to encode all the 24 Greek letters.

Masteriza [31]

Answer:

a. Rotational speed of the drill  = 375.96 rev/min

b. Feed rate  = 75 mm/min

c. Approach allowance  = 3.815 mm

d. Cutting time  = 0.67 minutes

e. Metal removal rate after the drill bit reaches full diameter. = 9525 mm³/min

Explanation:

Here we have

a. N = v/(πD) = 15/(0.0127·π) = 375.96 rev/min

b. Feed rate = fr = Nf = 375.96 × 0.2 = 75 mm/min

c. Approach allowance = tan 118/2 = (12.7/2)/tan 118/2 = 3.815 mm

d. Approach allowance T∞ =L/fr = 50/75 = 0.67 minutes

e. R = 0.25πD²fr = 9525 mm³/min.
